What "exactly" does the Brightness setting in the Print module do?
I know it's a controversial button, especially now that there are proofing options available. Also, since you're using it "blind" it's impossible to know how much or what it's really doing.
Does anyone know if it's e.g.. the same as going to quick develop and going up on "exposure", or "brightness", or "shadows"... How exactly is it brightening the image, and is +100 a full stop or how is it calibrated?
IIt's a gamma adjustment to lighten or darken the middle tones of an image...hence, the brightness.
So I might as well use the brightness control in Develop (or Quick Develop) to achieve the same thing in a more "visible" way?
Obviously there is NO brightness control in LR...is the print adjustment similar to an exposure adjustment or more like moving the "shadows" and "whites" adjustments (which if I understand corrrectly, moves tones above or below mid tones, but not highlights or blacks)?
